Map of E2M2
Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.


Other points of interest[edit]


  1. The door leading to the teleporter to the yellow key area counts as a secret and is impossible to miss. (sector 194)
  2. The nukage path to the yellow key has a secret door to the south (marked with a green wall) leading to a medikit, a stimpack, and a radiation shielding suit. On multiplayer there is also a spectre and another radiation shielding suit. (sector 210)


100% kills is not achievable as there is a cyberdemon at the start that is out of reach of the player.
